DETAILED DESCRIPTION

The present disclosure provides compositions and methods for modulating phosphatases and kinases, for example, receptor tyrosine kinases. Compositions and methods are provided for modulating Tie2, for example, to promote Tie2 phosphorylation, signaling, and/or activation. In some embodiments, the disclosure provides compositions and methods for targeting a phosphatase that modulates Tie2 signaling. In some embodiments, the phosphatase that modulates Tie2 signaling is human protein tyrosine phosphatase-beta (HPTP-β).

Compositions and methods are provided for modulating receptor tyrosine kinases, for example, to reduce receptor tyrosine kinase phosphorylation, signaling, and/or activation. In some embodiments, the disclosure provides compositions and methods for targeting a receptor tyrosine kinase agonist, e.g. vascular endothelial growth factor (VEGF). In some embodiments, the disclosure provides compositions and methods for targeting a receptor tyrosine kinase, e.g. a VEGF receptor.

In some embodiments, the present disclosure provides compositions and methods for targeting human protein tyrosine phosphatase-beta (HPTP-β) or vascular endothelial protein tyrosine phosphatase (VE-PTP or VEPTP), and vascular endothelial growth factor (VEGF). In some embodiments, the present disclosure provides multispecific compounds, agents, antibodies, fragments, or derivatives thereof that target HPTP-β (VE-PTP) and VEGF.

The agents disclosed herein can be used for the treatment of disorders that are characterized by, for example, vascular instability, angiogenesis, neovascularization, vascular leakage, and/or edema. The agents disclosed herein can be used for the treatment of, for example, vascular disorders, ocular disorders, cancers, renal disorders, and complications of diabetes.

HPTP-β/VE-PTP, Tie2, and Vascular Stability

HPTP-β is a member of the receptor-like family of the protein tyrosine phosphatases (PTPases). HPTP-β is a transmembrane protein found primarily in vascular endothelial cells that displays structural and functional similarity to cell adhesion molecules. Orthologues of HPTP-β are found in various species including, for example, zebrafish, chicken, dog, mouse, marmoset, and monkey. The orthologues are generally referred to as vascular endothelial protein tyrosine phosphatase (VE-PTP). HPTP-β (VE-PTP) can influence vascular stability through effects on Tie2-mediated signaling.

Tie2 (tyrosine kinase with immunoglobulin and epidermal growth factor homology domains 2) is a membrane receptor tyrosine kinase expressed primarily in vascular endothelial cells. Upstream factors can regulate Tie2 phosphorylation, influencing downstream signaling and vascular stabilization. Non-limiting examples of such factors include angiopoietin 1 (Ang1/Angpt1), angiopoietin 2 (Ang2/Angpt2), and HPTP-β (VE-PTP).

Ang1 is an agonist of Tie2. Binding of Ang1 to Tie2 promotes receptor phosphorylation and downstream signaling to induce vascular stabilization through highly organized angiogenesis, tightening of endothelial cell junctions, enhancement of endothelial viability, reduction of endothelial inflammation, and improvement of endothelial function.

Ang2 acts in a context-dependent antagonist or agonist of Tie2. During angiogenesis, Ang2 acts as a negative regulator of Ang1-Tie2 signaling.

HPTP-β (VE-PTP) is a phosphatase that can modulate Tie2 signaling. HPTP-β (VE-PTP) can dephosphorylate the Tie2 receptor. Under physiological conditions, HPTP-β (VE-PTP) regulates the duration of Tie2 phosphorylation. Inhibition of HPTP-β (VE-PTP), therefore, can result in increased Tie2 phosphorylation, increased Tie2-mediated signaling, and enhanced vascular stability. Inhibitors of HPTP-β (VE-PTP) are Tie2 activators. For example, a compound, inhibitor, antibody, antibody fragment, variant, or derivative thereof that binds HPTP-β (VE-PTP) can promote Tie2 phosphorylation, thereby activating Tie2 downstream signaling, and promoting vascular stability.

By the process described above, HPTP-β (VE-PTP) activity can contribute to, for example, disorders that are characterized by vascular instability, angiogenesis, neovascularization, vascular leakage, and/or edema. For example, HPTP-β (VE-PTP) activity can contribute to vascular disorders, ocular disorders, cancers, renal disorders, complications of diabetes, and other disorders. Inhibition of HPTP-β (VE-PTP) activity can reduce such disorders.

VEGF and Vascular Stability

Vascular endothelial growth factors (VEGFs) are primarily found in endothelial cells, and are implicated in pathological neovascularization in a number of diseases. The VEGFs are members of the cystine-knot growth factor superfamily, the PDGF family, and the VEGF family. The VEGFs can act as pro-angiogenic factors. The VEGF family consists of VEGF-A, VEGF-B, VEGF-C, VEGF-D and placental growth factor (PGF). Nine VEGF-A isoforms exist: VEGF₁₂₁, VEGF₁₄₅, VEGF₁₄₈, VEGF₁₆₂, VEGF₁₆₅, VEGF_(165b), VEGF₁₃, VEGF₁₈₉, and VEGF₂₀₆.

VEGF is a hypoxia-regulated gene, and VEGF levels are increased in hypoxic or ischemic conditions. VEGF is an agonist of VEGF receptors (VEGFRs). VEGFRs are receptor tyrosine kinases; binding of VEGF to a VEGFR can result in phosphorylation of the receptor, and subsequently of downstream signal transducers. VEGFR-mediated signaling can result in aberrant vasculogenesis, angiogenesis, and permeabilization of blood vessels, contributing to pathologic vascular instability. Thus, inhibition of VEGF can result in decreased VEGFR-mediated signaling and enhanced vascular stability. For example, an inhibitor, antibody, antibody fragment, variant, or derivative thereof that binds VEGF can reduce VEGFR ligation, thereby reducing VEGFR-mediated signaling, and promoting vascular stability. Non-limiting examples of agents that bind VEGF include aflibercept (Eylea®), a recombinant protein comprising the VEGF-binding portions of human VEGF receptors 1 and 2 fused to the Fc portion of human IgG1; brolucizumab, a humanized single-chain antibody fragment (scFv); RTH258, a humanized single-chain antibody fragment (scFv); ranibizumab (Lucentis®), a humanized monoclonal antibody fragment (Fab); bevacizumab (Avastin®), a humanized monoclonal antibody; conbercept, a recombinant fusion protein comprising extracellular domains from VEGF receptors 1 and 2 fused to the Fc portion of human IgG1; Abicipar, a designed ankyrin repeat protein (DARPin); MP0112, a DARPin; MP0250, a DARPin; CT-322, an adnectin; and PRS-050, an anticalin.

By the process described above, VEGF can contribute to, for example, disorders that are characterized by vascular instability, angiogenesis, neovascularization, vascular leakage, and/or edema. For example, VEGF can contribute to vascular disorders, ocular disorders, cancers, renal disorders, complications of diabetes, and other disorders. For example, ischemia in the eye can lead to increased VEGF production, resulting in vascular leakage and pathological neovascularization in the retina. Inhibition of VEGFR-mediated signaling can reduce such disorders.

Receptor Tyrosine Kinases (RTKs) and Receptor Tyrosine Kinase Agonists

Receptor tyrosine kinases (RTKs) are cell surface receptors that participate in the regulation of cell growth, differentiation, and survival. Binding of an agonist to a RTK can cause neighboring RTKs to associate with each other, forming dimers. Dimerization can cause cross-phosphorylation—each RTK in the dimer phosphorylates multiple tyrosine residues on the other RTK. Once cross-phosphorylated, the cytoplasmic tails of the RTKs can initiate signal transduction pathways, for example, by serving as docking platforms for various intracellular proteins. RTK signaling can lead to changes of gene transcription and expression in a cell.

Non-limiting examples of RTKs include AATK, AATYK, AATYK1, AATYK2, ACH, ALK, ARK, AXL, BDB, BDB1, BEK, BFGFR, BREK, Brt, CAK, CCK4, CD115, CD117, CD135, CD136, CD140a, CD140b, CD167, CD202b, CD220, CD221, CD246, CD309, CD331, CD332, CD333, CD334, CDHF12, CDHR16, CDwl36, CEK, CEK2, CEK3, c-Eyk, CFD1, C-FMS, C-Kit, cprk, c-ros-1, CSF1R, CSFR, D3S3195, DDR1, DDR2, DFNB97, DKFZp761P1010, Dtk, ECT1, EDDR1, EGFR, EphA10, EphA1-8.

Antibodies and Antigen-Binding Compounds.

The basic four chain antibody unit comprises two identical heavy chain (H) polypeptide sequences and two identical light chain (L) polypeptide sequences. Each of the heavy chains can comprise one N-terminal variable (V_(H)) region and three or four C-terminal constant (C_(H)1, C_(H)2, C_(H)3, and C_(H)4) regions. Each of the light chains can comprise one N-terminal variable (V_(L)) region and one C-terminal constant (C_(L)) region. The light chain variable region is aligned with the heavy chain variable region and the light chain constant region is aligned with heavy chain constant region C_(H1). The pairing of a heavy chain variable region and light chain variable region together forms a single antigen-binding site. Each light chain is linked to a heavy chain by one covalent disulfide bond. The two heavy chains are linked to each other by one or more disulfide bonds depending on the heavy chain isotype. Each heavy and light chain also comprises regularly-spaced intrachain disulfide bridges. The C-terminal constant regions of the heavy chains comprise the Fc region of the antibody, which mediate effector functions, for example, through interactions with Fc receptors or complement proteins. FIG. 1 provides a simple representative schematic basic four chain antibody unit; light chain sequences are represented by “SEQ A”. Heavy chain sequences are represented by “SEQ B”, —S—S— denotes disulfide bonds, N and C denote N- and C-termini, respectively.

The light chain can be designated kappa or lambda based on the amino acid sequence of the constant region. The heavy chain can be designated alpha, delta, epsilon, gamma, or mu based on the amino acid sequence of the constant region. Antibodies are categorized into five immunoglobulin classes, or isotypes, based on the heavy chain. IgA comprises alpha heavy chains, IgD comprises delta heavy chains, IgE comprises epsilon heavy chains, IgG comprises gamma heavy chains, and IgM comprises mu heavy chains. Antibodies of the IgG, IgD, and IgE classes comprise monomers of the four chain unit described above (two heavy and two light chains), while the IgM and IgA classes can comprise multimers of the four chain unit. The alpha and gamma classes are further divided into subclasses on the basis of differences in the sequence and function of the heavy chain constant region. Subclasses of IgA and IgG expressed by humans include IgG1, IgG2, IgG3, IgG4, IgA1 and IgA2.

The constant regions are minimally involved in antigen binding. Rather, the constant regions can mediate various effector functions. Different IgG isotypes or subclasses can be associated with different effector functions or therapeutic characteristics, for example, because of interactions with different Fc receptors and/or complement proteins. Antibodies comprising Fc regions that engage activating Fc receptors can, for example, participate in antibody-dependent cell-mediated cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), complement-dependent cytotoxicity (CDC), induction of signaling through immunoreceptor tyrosine-based activation motifs (ITAMs), and induction of cytokine secretion. Antibodies comprising Fc regions that engage inhibitory Fc receptors can, for example, induce signaling through immunoreceptor tyrosine-based inhibitory motifs (ITIMs).

Different antibody subclasses comprise different abilities to elicit immune effector functions. For example, IgG1 and IgG3 can effectively recruit complement to activate CDC, IgG2 elicits minimal ADCC. IgG4 has a lesser ability to trigger immune effector functions. Modifications to the constant regions can also affect antibody characteristics, for example, enhancement or reduction of Fc receptor ligation, enhancement or reduction of ADCC, enhancement or reduction of ADCP, enhancement or reduction of CDC, enhancement or reduction of signaling through ITAMs, enhancement or reduction of cytokine induction, enhancement or reduction of signaling through ITIMs, enhancement or reduction of half-life, or enhancement or reduction of coengagement of antigen with Fc receptors. Modifications can include, for example, amino acid mutations, altering post-translational modifications (e.g., glycosylation), combining domains from different isotypes or subclasses, or a combination thereof.

A compound or antibody of the disclosure can comprise constant regions or Fc regions that are selected or modified to provide suitable antibody characteristics, for example, suitable characteristics for treating a disease or condition as disclosed herein. In some embodiments, IgG1 can be used, for example, to promote immune activation effector functions (e.g., ADCC, ADCP, CDC, ITAM signaling, cytokine induction, or a combination thereof for the treatment of a cancer). In some embodiments, IgG4 can be used, for example, in cases where antagonistic properties of the antibody in the absence of immune effector functions are desirable (e.g., for treatment of ocular disorders).

The variable (V) regions mediate antigen binding and define the specificity of a particular antibody for an antigen. The variable region comprises relatively invariant sequences called framework regions, and hypervariable regions, which differ considerably in sequence among antibodies of different binding specificities. The variable region of each antibody heavy or light chain comprises four framework regions separated by three hypervariable regions. The variable regions of heavy and light chains fold in a manner that brings the hypervariable regions together in close proximity to create an antigen binding site. The four framework regions largely adopt an f3-sheet configuration, while the three hypervariable regions form loops connecting, and in some cases forming part of, the f3-sheet structure.

Within hypervariable regions are amino acid residues that primarily determine the binding specificity of the antibody. Sequences comprising these residues are known as complementarity determining regions (CDRs). One antigen binding site of an antibody comprises six CDRs, three in the hypervariable regions of the light chain, and three in the hypervariable regions of the heavy chain. The CDRs in the light chain are designated L1, L2, and L3, while the CDRs in the heavy chain are designated H1, H2, and H3. CDRs can also be designated LCDR1, LCDR2, LCDR3, HCDR1, HCDR2, and HCDR3, respectively. The contribution of each CDR to antigen binding varies among antibodies. CDRs can vary in length. For example, CDRs are often 5 to 14 residues in length, but CDRs as short as 0 residues or as long as 25 residues or longer exist.

Several methods are used to predict or designate CDR sequences. These methods can use different numbering systems, for example, because sequence insertions and deletions are numbered differently.

The Kabat method was developed by aligning a limited number of antibody sequences and determining the positions of the most variable residues. Based on the alignment, a numbering scheme was introduced for residues in the variable regions. This numbering scheme can be used to determine the positions marking the beginning and the end of each CDR. One iteration of the Kabat numbering system identifies CDRs in the light chain variable region using the following residue positions: LCDR1 around residues 24-34; LCDR2 around residues 50-56; and LCDR3 around residues 89-97. One iteration of the Kabat numbering system identifies CDRs in the heavy chain variable region using the following residue positions: HCDR1 around residues 31-35; HCDR2 around residues 50-65; and HCDR3 around residues 95-102.

The Chothia method was developed based on analysis of three dimensional antibody structures. The analysis determined that hypervariable loops adopt a restricted set of conformations based on the presence of certain residues at key positions in CDRs and flanking framework regions. This method uses a similar numbering scheme as the Kabat method, but numbers insertions and deletions differently. One iteration of the Chothia numbering system identifies CDRs in the light chain variable region using the following residue positions: LCDR1 around residues 24-34; LCDR2 around residues 50-56; and LCDR3 around residues 89-97. One iteration of the Chothia numbering system identifies CDRs in the heavy chain variable region using the following residue positions: HCDR1 around residues 26-34; HCDR2 around residues 52-56; and HCDR3 around residues 95-102.

The IMGT method (International ImMunoGeneTics database) was developed by integrating existing definitions of framework regions and CDRs, structural data, and data from alignment of antibody variable region sequences. This integration led to the identification of conserved residues in the framework regions that can be used as reference points for identifying CDRs. Examples of conserved residues in variable regions include cysteine at approximately residue 23 (in framework region 1), tryptophan at approximately residue 41 (in framework region 2), a hydrophobic amino acid at approximately residue 89 (in framework region 3), cysteine at approximately residue 104 (in framework region 3), and phenylalanine or tryptophan at approximately residue 118 (in framework region 4). CDRs can be identified in a sequence encoding an antibody variable region of interest by using a computational alignment-based algorithm.

The IMGT method of numbering consistently assigns the same numbers to the conserved amino acids, but the lengths of CDRs and framework regions are permitted to vary. Therefore, IMGT numbering of residues is not necessarily sequential. The length of CDRs identified by the IMGT method can vary. For example, LCDR1 or HCDR1 can be about 5 to about 12 amino acids, LCDR2 or HCDR2 can be about 0 to about 10 amino acids, and LCDR3 or HCDR3 can be about 5 to about 91 amino acids.

The Paratome method was developed based on multiple structural alignments of available antibody-antigen complexes. The structural positions that bind antigen were found to be similar among the examined antibodies, and antibody sequences from the data set were annotated with Antigen Binding Regions (ABRs, similar to CDRs). ABRs in a query sequence can be identified using a computational tool, which first aligns the query sequence against antibodies with solved antibody-antigen structures, then infers the positions of ABRs based on the alignment. Antibodies with solved structures can also have ABRs identified using a structural, rather than sequence-based, alignment method.

A subset of residues within CDRs contacts an antigen. These residues that contact antigen can be referred to as specificity-determining residues (SDRs). However, residues other than SDRs can contribute to binding activity by helping to maintain the conformation of the binding site. The number of SDRs in an antibody can vary based on the size and type of antigen that is recognized, for example, between 0-14 SDRs can be found within a CDR. SDRs can be enriched in some residues, such as tyrosine, serine, tryptophan, and asparagine.

A monoclonal antibody can be obtained from a population of substantially-homogeneous antibodies, i.e., the individual antibodies comprising the population are identical except for possible naturally-occurring mutations that can be present in minor amounts. In contrast to polyclonal antibody preparations, which include different antibodies directed against different epitopes, each monoclonal antibody is directed against a single epitope.

A compound herein can be a monoclonal antibody, for example, a chimeric antibody wherein a portion of the heavy and/or light chain is identical to or homologous to a corresponding sequence in an antibody derived from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chain(s) is identical or homologous to a corresponding sequence in an antibody derived from another species or belonging to another antibody class or subclass, or an antigen-binding fragment of such an antibody.

An antibody fragment or antigen-binding fragment can comprise a portion of an antibody, for example, the antigen-binding or variable region of the intact antibody. Non-limiting examples of antibody fragments include Fab, Fab′, F(ab′)₂, dimers and trimers of Fab conjugates, Fv, scFv, minibodies, dia-, tria-, and tetrabodies, and linear antibodies. Fab and Fab′ are antigen-binding fragments that can comprise the V_(H) and C_(H)1 domains of the heavy chain linked to the V_(L) and C_(L) domains of the light chain via a disulfide bond. A F(ab′)₂ can comprise two Fab or Fab′ that are joined by disulfide bonds. A Fv can comprise the V_(H) and V_(L) domains held together by non-covalent interactions. A scFv (single-chain variable fragment) is a fusion protein that can comprise the V_(H) and V_(L) domains connected by a peptide linker. Manipulation of the orientation of the V_(H) and V_(L) domains and the linker length can be used to create different forms of molecules that can be monomeric, dimeric (diabody), trimeric (triabody), or tetrameric (tetrabody). Minibodies are scFv-C_(H)3fusion proteins that assemble into bivalent dimers.

Non-limiting examples of epitopes include amino acids, sugars, lipids, phosphoryl, and sulfonyl groups. An epitope can have specific three-dimensional structural characteristics, and/or specific charge characteristics. Epitopes can be conformational or linear.

For human administration, monoclonal antibodies generated from non-human species can be further optimized by a humanization process to reduce the likelihood of immunogenicity while preserving target specificity. Humanization processes involve the incorporation of human DNA to the genetic sequence of the genes that produce the isolated antibodies. The recombinant DNA is cloned and expressed in cells for large-scale production of the newly humanized antibodies.

An example of a humanized antibody is a modified chimeric antibody. A chimeric antibody can be generated as described above. The chimeric antibody is further mutated outside of the CDRs to substitute non-human sequences in the variable regions with the homologous human sequences. Another example of a humanized antibody is a CDR-grafted antibody, in which non-human CDR sequences are introduced into the human heavy and light chain variable sequences of a human antibody scaffold to replace the corresponding human CDR sequences.

A humanized antibody can be produced in mammalian cells, bioreactors, or transgenic animals, such as mouse, chicken, sheep, goat, pig, or marmoset. The transgenic animal can have a substantial portion of the human antibody-producing genome inserted into the genome of the animal.

In addition to antibodies and antibody fragments, other antigen-binding compounds can also bind target molecules. Non-limiting examples of non-antibody-derived antigen-binding compounds include ankyrin proteins, ankyrin repeat proteins, designed ankyrin repeat proteins (DARPins), affibodies, avimers, adnectins, anticalins, Fynomers, Kunitz domains, knottins, β-hairpin mimetics, and receptors and derivatives thereof, e.g. VEGF receptors, or the VEGF-binding portions of human VEGF receptors 1 and 2.

Designed ankyrin repeat proteins (DARPins) can be protein scaffolds based on ankyrin repeat proteins. A DARPin can comprise one or more ankyrin repeats that comprise a shared sequence and/or structural motif. The individual ankyrin repeats can comprise a shared sequence and/or structural motif despite comprising mutations, substitutions, additions and/or deletions when compared to one other. A DARPin can comprise, for example, about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 ankyrin repeats, or more. A DARPin can comprise an N-terminal capping repeat, one or more internal ankyrin repeats, and a C-terminal capping repeat. Each ankyrin repeat can comprise framework residues and protein-interaction residues. The framework residues can contribute to structure or folding topology, for example, the structure of an ankyrin repeat or interaction with a neighboring ankyrin repeat. Protein-interaction residues can contribute to binding of a target molecule, for example, via direct interaction with the target molecule, or by stabilizing directly-interacting residues in a conformation that allows binding.

Polyvalent, Multispecific Compounds

Antigen-binding compounds can be combined to generate polyvalent and/or multispecific compounds. Such polyvalent and/or multispecific compounds can have advantages over the parent compounds administered individually. These advantages can include, for example, a simpler dosing regimen, longer half-life within a subject, and the ability to bind target antigens in close proximity.

Multispecific antibodies can be produced by a number of methods. In one method, monospecific antibodies or derivatives thereof can be chemically coupled, for example, via chemical coupling of two IgG antibody units into a conjugate.

In another method, cloning techniques can be used to append additional antigen binding domain(s) to a conventional IgG antibody or derivative thereof. An additional antigen-binding domain can be, for example, a single variable domain (sVD), a single-chain variable fragment (scFv), a single-chain Fab, a peptide, an ankyrin protein, an ankyrin repeat protein, a designed ankyrin repeat protein (DARPin), an affibody, an avimer, an adnectin, an anticalin, a Fynomer, a Kunitz domain, a knottin, a β-hairpin mimetic, a tetrameric polyethylene oxide clustered peptide, a peptide derived from one or more receptors (e.g. VEGF receptors, or the VEGF-binding portions of human VEGF receptors 1 and 2), or a derivative thereof.

The additional antigen-binding domain (e.g., sVD, scFv, single-chain Fab, peptide, ankyrin protein, ankyrin repeat protein, DARPin, affibody, avimer, adnectin, anticalin, Fynomer, Kunitz domain, knottin, β-hairpin mimetic, tetrameric polyethylene oxide clustered peptide, or peptide derived from one or more receptors) can be appended to the N or C-terminus of the light chain and/or heavy chain of the IgG or Fab, for example, via a peptide linker. In some embodiments, a scFv can be appended to the C-termini of the heavy chains of an IgG to provide a tetravalent bispecific antibody. A scFv can be appended to the C-termini of the light chains of an IgG to provide a tetravalent bispecific antibody. A scFv can be appended to the C-termini of the light chains and the C-termini of the heavy chains of an IgG, to provide a hexavalent bispecific antibody. In some embodiments, a DARPin can be appended to the C-termini of the heavy chains of an IgG to provide a tetravalent bispecific antibody. A DARPin can be appended to the C-termini of the light chains of an IgG to provide a tetravalent bispecific antibody. A DARPin can be appended to the C-termini of the light chains and the C-termini of the heavy chains of an IgG, to provide a hexavalent bispecific antibody. Additional examples of multispecific antibodies produced by cloning techniques include: (i) DVD-Ig™ (dual variable domain immunoglobulin, tandem linkage of the second V_(H) and V_(L) to the N-termini of HC and LC, respectively), (ii) Tandemab (tandem linkage of 2 V_(H)-C_(H)1 in combination of common LC), (iii) DNL (natural association of 2 antibodies or antibody fragments anchored with DDD (dimerization and docking domain) from PKA (protein kinase A) and AD (anchoring domain) from A-kinase anchor protein (AKAP), respectively), (iv) LUZ-Y (leucine zipper tethered at the C-termini of HC and later proteolytically removed), (v) 2-in-1-IgG (same LC and HC capable of dual recognition), and (vi) mAb² (engineered loops in C_(H)3 domain of IgG to obtain second specificity).

Another class of multispecific antibodies can be characterized by structures with variable domains or scFvs as the building blocks. Non-limiting examples of such multispecific antibodies include two V_(H) domains joined in tandem, diabodies (heterodimers containing 2 polypeptide chains encoding V_(L)A-V_(H)B and V_(H)A-V_(L)B in the order of V_(H)-V_(L) or V_(L)—V_(H) with a linker of 5 amino acids), dsDbs (interchain disulfide bond between V_(L) and V_(H) of the same antibody), DARTs (dual-affinity re-targeting, interchain disulfide bond between 2 V_(L)), scDbs (single chain Diabody), tandAbs (Diabody dimer via flexible linkers in between), and 2 scFvs connected in tandem by an adjustable linker.

Another class of multispecific antibodies can contain different antigen binding fragments, while retaining the basic IgG structure. Such antibodies can comprise, for example, two distinct heavy chains and/or two distinct light chains. Various techniques can be used to promote pairing of desirable light and heavy chain combinations, rather than random chain associations. Non-limiting examples of such techniques include use of a common light chain, orthogonal Fab interface (complementary mutations introduced at LC and HC interface in one Fab and no change to the other Fab), CrossMab (wherein one Fab V_(H) or C_(H)1 domain(s) can be switched with the partner V_(L) or C_(L) domain(s), with the other Fab untouched), and replacing the Fab with a single chain antigen-binding domain. Further examples include engineering strategies that can introduce mutations into the C_(H)3 domains to promote heterodimerization based on steric or electrostatic complementarity. The “knobs in holes” approach can involve creating a “knob” by replacing threonine at position 366 with a bulky tryptophan residue on one heavy chain, and making a corresponding “hole” by triple mutations (T366S, L368A and Y407V) on the partner heavy chain. Another approach can involve creating alternating human IgG and IgA fragments in C_(H)3 to provide the so-called SEEDbody (Strand-Exchange Engineered Domain) to guide heavy chain heterodimerization.

Antibodies or antigen-binding compounds specific for VEGF can be combined with antibodies or antigen-binding compounds specific to HPTP-β (VE-PTP) to form multispecific compounds, such as bispecific compounds that bind VEGF and HPTP-β (VE-PTP). Any compounds in this disclosure specific for VEGF can be combined with any compounds in this disclosure specific to HPTP-β (VE-PTP). Any of the compounds in this disclosure specific for VEGF or HPTP-β (VE-PTP) can be modified as necessary for the generation of a multispecific compound. Non-limiting examples of modifications necessary for the generation of a multispecific compound include the addition of amino acid residues, the removal of amino acid residues, the replacement of amino acid residues, and the use of linkers. In some embodiments, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, or more residues can be added to an N-terminus and/or a C-terminus of a sequence disclosed herein, and the resulting sequence can be used in the generation of a multi-specific construct. In some embodiments, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, or more residues can be removed from an N-terminus and/or a C-terminus of a sequence disclosed herein, and the remaining sequence can be used in the generation of a multi-specific construct. For example, N- and/or C-terminal residues can be removed from SEQ ID NO: 173 (e.g., to generate SEQ ID NO: 244), and the truncated sequence can be used in a multi-specific construct. In some embodiments, the sequences in any of SEQ ID NOS: 13-20 or 246-253 can be modified. For example, one or more C-terminal residues can be removed (e.g., the C-terminal lysine can be removed from any of SEQ ID NOS: 13-16 or 246-249, and the remaining residues (residues 1-467) can be used in a multi-specific construct).

A compound described herein can include a linker between different domains of the compound. A linker can be a chemical bond, for example, a covalent bond or a non-covalent bond. A linker as described herein can include a flexible or rigid linker.

A linker of the disclosure can include a chemical linker. For example, two amino acid sequences of the disclosure can be connected together by a chemical linker. Each chemical linker of the disclosure can be alkylene, alkenylene, alkynylene, heteroalkylene, cycloalkylene, heterocycloalkylene, arylene, or heteroarylene, any of which is optionally substituted. In some embodiments, a chemical linker of the disclosure can be an ester, ether, amide, thioether, or polyethyleneglycol (PEG). In some embodiments, a linker can reverse the order of the amino acids sequence in a compound, for example, so that the amino acid sequences linked by the linked are head-to-head, rather than head-to-tail. Non-limiting examples of such linkers include diesters of dicarboxylic acids, such as oxalyl diester, malonyl diester, succinyl diester, glutaryl diester, adipyl diester, pimetyl diester, fumaryl diester, maleyl diester, phthalyl diester, isophthalyl diester, and terephthalyl diester. Non-limiting examples of such linkers include diamides of dicarboxylic acids, such as oxalyl diamide, malonyl diamide, succinyl diamide, glutaryl diamide, adipyl diamide, pimetyl diamide, fumaryl diamide, maleyl diamide, phthalyl diamide, isophthalyl diamide, and terephthalyl diamide. Non-limiting examples of such linkers include diamides of diamino linkers, such as ethylene diamine, 1,2-di(methylamino)ethane, 1,3-diaminopropane, 1,3-di(methylamino)propane, 1,4-di(methylamino)butane, 1,5-di(methylamino)pentane, 1,6-di(methylamino)hexane, and pipyrizine.

Non-limiting examples of optional substituents include hydroxyl groups, sulfhydryl groups, halogens, amino groups, nitro groups, nitroso groups, cyano groups, azido groups, sulfoxide groups, sulfone groups, sulfonamide groups, carboxyl groups, carboxaldehyde groups, imine groups, alkyl groups, halo-alkyl groups, alkenyl groups, halo-alkenyl groups, alkynyl groups, halo-alkynyl groups, alkoxy groups, aryl groups, aryloxy groups, aralkyl groups, arylalkoxy groups, heterocyclyl groups, acyl groups, acyloxy groups, carbamate groups, amide groups, ureido groups, epoxy groups, and ester groups.

A linker can be a peptide. A linker can comprise a linker sequence, for example, a linker peptide sequence. A linker sequence can be, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 51, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, or 70 amino acid residues in length.

A flexible linker can have a sequence containing stretches of glycine and serine residues. The small size of the glycine and serine residues provides flexibility, and allows for mobility of the connected functional domains. The incorporation of serine or threonine can maintain the stability of the linker in aqueous solutions by forming hydrogen bonds with the water molecules, thereby reducing unfavorable interactions between the linker and protein moieties.

Flexible linkers can also contain additional amino acids such as threonine and alanine to maintain flexibility, as well as polar amino acids such as lysine and glutamine to improve solubility.

A flexible linker can comprise repeats of SEQ ID NO: 42 (GGGS), for example, SEQ ID NOS: 42-55. A flexible linker can comprise repeats of SEQ ID NO: 31 (GGGGS), for example, SEQ ID NOS: 31-41. Several other types of flexible linkers, including SEQ ID NO: 59 (KESGSVSSEQLAQFRSLD) and SEQ ID NO: 60 (EGKSSGSGSESKST), can also be used. The SEQ ID NO: 61 (GSAGSAAGSGEF) linker can also be used, in which large hydrophobic residues are minimized to maintain good solubility in aqueous solutions. The length of the flexible linkers can be adjusted to allow for proper folding or to achieve optimal biological activity of the fused proteins.

A rigid linker can have, for example, an alpha helix-structure. An alpha-helical rigid linker can act as a spacer between protein domains. A rigid linker can comprise repeats of SEQ ID NO: 62 (EAAAK), for example, SEQ ID NOS: 62-66. A rigid linker can comprise repeats of SEQ ID NO: 67 (EAAAR), for example, SEQ ID NOS: 67-72. A rigid linker can have a proline-rich sequence, (XP)n, with X designating alanine, lysine, glutamine, or any amino acid. The presence of proline in non-helical linkers can increase stiffness, and allow for effective separation of protein domains.

A linker can comprise any of the sequences disclosed in TABLE 18, which can be used to link any portion of a compound disclosed herein to any portion of another compound disclosed herein:

Pharmaceutical compositions can also include one or more additional active ingredients such as antimicrobial agents, anti-inflammatory agents, and anesthetics.

Non-limiting examples of pharmaceutically-acceptable carriers include saline, Ringer's solution, and dextrose solution. In some embodiments, the pH of the solution can be from about 5 to about 8, and can be from about 7 to about 7.5. Further carriers include sustained release preparations such as semipermeable matrices of solid hydrophobic polymers containing the compound. The matrices can be in the form of shaped articles, for example, films, liposomes, microparticles, or microcapsules.

Compositions suitable for topical administration can be used. In some embodiments, compositions of the disclosure can comprise a liquid comprising an active agent in solution, in suspension, or both. Liquid compositions can include gels. A liquid composition can be, for example, aqueous. A composition is an in situ gellable aqueous composition. In iteration, the composition is an in situ gellable aqueous solution. Such a composition can comprise a gelling agent in a concentration effective to promote gelling upon contact with the eye or lacrimal fluid in the exterior of the eye. Aqueous compositions can have ophthalmic ally-compatible pH and osmolality. The composition can comprise an ophthalmic depot formulation comprising an active agent for subconjunctival administration. Microparticles comprising an active agent can be embedded in a biocompatible, pharmaceutically-acceptable polymer or a lipid encapsulating agent. The depot formulations can be adapted to release all or substantially all the active material over an extended period of time. The polymer or lipid matrix, if present, can be adapted to degrade sufficiently to be transported from the site of administration after release of all or substantially all the active agent. The depot formulation can be a liquid formulation, comprising a pharmaceutical acceptable polymer and a dissolved or dispersed active agent. Upon injection, the polymer forms a depot at the injections site, for example, by gelifying or precipitating. The composition can comprise a solid article that can be inserted in a suitable location in the eye, such as between the eye and eyelid or in the conjuctival sac, where the article releases the active agent. Solid articles suitable for implantation in the eye in such fashion can comprise polymers and can be bioerodible or non-bioerodible.

Pharmaceutical formulations can include additional carriers, as well as thickeners, diluents, buffers, preservatives, and surface active agents in addition to the agents disclosed herein.

Mouse Models Oxygen-Induced Ischemic Retinopathy Model

The oxygen-induced ischemic retinopathy model can be considered to mimic aspects of proliferative retinal neovascularization and proliferative diabetic retinopathy. One week old mice can be placed in an airtight chamber and exposed to hyperoxia (75±3% oxygen) for five days, resulting in hyperoxia-induced neovascularization, for example, at the junction between the vascularized and avascular retina between postnatal day 17 and 21. Mice can be dosed with a compound of interest, for example, an antibody or compound of the disclosure, to determine the effect on neovascularization and/or vascular leakage. Neovascularization and/or vascular leakage can be assessed as described below.

Rho/VEGF Mouse Model

The Rho/VEGF mouse model can mimic aspects of neovascular age-related macular degeneration. Transgenic mice with vascular endothelial growth factor (VEGF) expression driven by the rhodopsin promoter (rho/VEGF mice) can develop retinal neovascularization, retinal angiomatous proliferation, and retinal vascular leakage. In rho/VEGF mice, VEGF expression in photoreceptors can begin between postnatal days 5 and 10, the period when the deep capillary bed is developing. Neovascularization can originate from the deep capillary bed of the retina and grow into the subretinal space. Mice can be dosed with a compound of interest, for example, an antibody or compound of the disclosure, to determine the effect on neovascularization and/or vascular leakage. Neovascularization and/or vascular leakage can be assessed as described below.

Tet/Opsin/VEGF Mouse Model

Mice with a VEGF under the control of a reverse tetracycline transactivator (rtTA) inducible promoter coupled to the rhodopsin promoter (Tet/opsin/VEGF mice) can be used as an inducible model of neovascularization, retinal vascular leakage, and retinal detachment. In these mice, VEGF transgene expression in the retina can be induced by administering doxycycline. Neovascularization can be evident by three to four days after VEGF induction. Neovascularization can be more extensive, and can cause outer retinal folds followed by total retinal detachment within about five days. Mice can be dosed with a compound of interest, for example, an antibody or compound of the disclosure, to determine the effect on neovascularization, vascular leakage, and/or retinal detachment. Neovascularization and/or vascular leakage can be assessed as described below. To assess retinal detachment, eyes can be frozen in cutting temperature embedding solution, ten micron sections cut through the entire eye, and sections stained with Hoechst. Sections can be examined by light microscopy, the mean length of the retinal detachment per section measured by image analysis, and the detached percentage of the retina calculated.

Tet/Opsin/Ang2 Mouse Model

Tet/opsin/Ang2 mice have inducible expression of Ang2 in the retina. These mice can be used to study the impact of Ang2 expression in various experimental conditions. For example, Tet/opsin/Ang2 mice can be used to determine the effect of Ang2 expression on neovascularization when VEGF levels are high versus low, or the effect of Ang2 expression in the oxygen induced ischemic retinopathy model. Mice can be dosed with a compound of interest, for example, an antibody or compound of the disclosure, to determine the impact of Ang2 expression on therapeutic efficacy.

Laser-Induced Choroidal Neovascularization Model

The laser-induced choroidal neovascularization model can be considered to mimic aspects of neovascular age-related macular degeneration. Anesthetized mice can have their pupils dilated, and burns can be delivered, for example, to the retina by a krypton laser using a slit lamp system and a cover glass as a contact lens. Multiple burns can be produced in a single eye, for example, burns in three locations per eye. Burns can cause rupture of Bruch's membrane. Choroidal neovascularization can be assessed at various time points after laser treatment, for example, one week, two weeks, or four weeks after laser treatment. Mice can be dosed with a compound of interest, for example, an antibody or compound of the disclosure, to determine the effect on neovascularization. Eyecups can be stained with FITC-labeled GSA, choroids flat mounted, and the area of choroidal neovascularization at each Bruch's membrane rupture site measured with fluorescence microscopy and image analysis. Neovascularization and/or vascular leakage can also be assessed as described below.

Assessment of Neovascularization

Neovascularization can be assessed using a range of techniques.

Fluorescein angiograms can be done by taking serial fundus photographs after injection of a dye to reveal blood vessels, allowing identification of the presence, location, and size of a neovascular complex. For example, an intraperitoneal injection of 0.3 mL of 1% fluorescein sodium can be given, serial fundus photographs taken, and the choroidal neovascularization area, total lesion area, and leakage area can be measured.

Eyes can be processed for evaluation by fluorescent, light, or electron microscopy. For example, mice can be perfused with fluorescently labelled dextran, or eyes can be injected with GSA or antibodies targeting PECAM. Eyes can be processed for observation under a fluorescent microscope, and the extent of neovascularization can be quantified, for example, by quantifying the area of neovascularization per retina, by quantifying the area of neovascularization at each Bruch's membrane rupture site, or by quantifying the number of nuclei of new vessels extending from the retina into the vitreous.

The area of retinal neovascularization can be determined, for example, using FITC-labeled GSA lectin and fluorescence microscopy. Eyes can be fixed in 10% formalin, dissected intact, washed with PBS, blocked in 8% swine serum, and stained with FITC-labeled GSA lectin for a time appropriate to stain retinal neovascularization and hyaloid vessels, but not normal retinal vessels (e.g., 40-50 minutes). Retinas can be flat mounted, digital images can be obtained with a fluorescent microscope and merged into a single image of the entire retina. Software can be used to measure the area of neovascularization per retina.

The area of subretinal neovascularization can be determined, for example, using FITC-labeled GSA lectin and fluorescence microscopy. Eyes can be fixed in 10% formalin, and retinas can be dissected, blocked with 5% swine serum, stained with FITC-conjugated GSA for two hours to stain vascular cells, and flat mounted with the photoreceptor side up. The area of subretinal neovascularization can be measured with fluorescence microscopy and image analysis.

Assessment of Retinal Vascular Leakage

Retinal vascular leakage can be assessed by measuring extravasated serum albumin using an immunofluorescent technique. For example, eyes can be fixed in 10% formalin, retinas can be dissected, washed, blocked, and stained using an anti-albumin antibody and a fluorescently-conjugated secondary antibody. The vessels can be labeled by counterstaining with GSA lectin, and retinas flat mounted. Retinas can be examined by fluorescence microscopy, and the area of albumin staining determined by image analysis. Retinal vascular leakage is relevant to, for example, diabetic macular edema and macular edema due to retinal vein occlusion.

Miles Assay for Vascular Leakage

The Miles assay can be used to assess vascular leakage in dermal subcutaneous blood vessels. Evans blue is a dye that binds albumin. Under physiologic conditions the endothelium is impermeable to albumin, so Evans blue bound albumin remains restricted within blood vessels. In pathologic conditions that promote increased vascular permeability, endothelial cells partially lose close contacts. The endothelium becomes permeable to small proteins such as albumin. Mice can be injected intravenously with 1% Evans blue dye in PBS, and injected intradermally with VEGF. Thirty minutes after intradermal injections, tissue at the intradermal injection sites can be excised and extracted in formamide to assess Evans blue dye extravasation. Vascular leakage can be quantified by measurement of the dye incorporated per milligram of tissue, for example, using optical density measurements and a standard curve. Mice can be dosed with a compound of interest, for example, an antibody or compound of the disclosure, to determine the effect on vascular leakage.

Cancer Models

The efficacy of a compound or antibody of the disclosure as a treatment for cancer can be tested in a range of cancer models. In some cancer models, cancer cells from a cell line can be implanted in a recipient animal, for example, a mouse. Non-limiting examples of suitable mouse strains include C57BL6, BALB/C, C3H, FVB/N, and FVB/N-Tg(IMTV-PyVT)634Mul. Non-limiting examples of suitable cancer cell lines include 4T1, E0771, and P0008. Cells of the 4T1 or E0771 cell lines can, for example, be implanted into a mammary pad as a model of breast cancer. 4T1 or E0771 cells can be implanted, for example, into the third mammary fat pad of female nude mice.

The size of solid tumors can be measured with calipers and tumor volume calculated. Tumors can be processed for histopathological evaluation or fluorescence microscopy, to assess, for example, tumor area, tumor grade, metastases count, metastases area, the number of cell nuclei per tumor focus, intratumoral vessel diameter, intratumoral vessel density, tumor vascular maturity, perivascular cell coverage, proximity between perivascular cells and endothelial cells, or to grade tumors foci as intravascular or extravascular.

Spontaneous metastasis models can be used to study the effects of a compound or antibody of the disclosure on metastasis. After tumor implant, a primary tumor can be resected (e.g., upon reaching 5 mm in size), and the animal later evaluated macroscopically or histopathologically for metastases, for example, to determine the number and size of metastases in the lungs, liver, lymph nodes, and bones.

To evaluate the impact of vessel stability on metastasis, a model can be used wherein tumor cells can be injected intravenously, and the animal subsequently evaluated for intravascular versus extravasated metastases. For example, 4T-1 cells can be injected intravenously, and the lungs processed for histopathologic evaluation to quantify intravascular versus extravascular metastases.

Metastases can be counted and measured macroscopically, for example, by immersing lungs in Bouin's solution, then examining them with a stereomicroscope.

To measure tumor vessel permeability in vivo, intravital multiphoton microscopy can be used. Animals can be injected with fluorescently labeled bovine serum albumin, for example, pre-treatment and post-treatment time points. At each time point, two distinct regions within the tumor can be selected and a 200 micron image stack recording BSA fluorescence taken through each region every ten minutes for an hour, using a multiphoton laser scanning microscope. The analysis approach can involve three-dimensional vessel tracing to create vessel metrics and a three-dimensional map of voxel intensity versus distance to the nearest vessel over time. Images can be corrected for sample movement over time with three-dimensional image registration. The normalized transvascular flux can be calculated.

Example 14: Bispecific Antibodies that Activate Tie2

Human Umbilical Cord Endothelial Cells (HUVECs) were seeded onto T75 flasks coated with porcine gelatin. Cell maintenance was performed using complete medium (EGM or EGM-2) and sub-cultured using Trypsin/EDTA into 100 mm dishes. After 3 days, the 100 mm dishes were rinsed, and treated in basal medium (EBM, EBM-2, OptiMEM I) for 30 minutes at 37° C./5% CO₂ with one of the following antibodies at 5 or 50 nM as indicated in FIG. 19: (i) HC2:LC1, a humanized monoclonal antibody specific for HPTP-β; (ii) HC2-BRO:LC1, a tetravalent bispecific antibody comprising brolucizumab-derived VEGF-binding domains fused to the C-termini of the heavy chains of HC2:LC1; (iii) HC2-AFL:LC1, a tetravalent bispecific antibody comprising aflibercept-derived VEGF-binding domains fused to the C-termini of the heavy chains of HC2:LC1; (iv) HC2-BRO:LC1-BRO, a hexavalent antibody comprising brolucizumab-derived VEGF-binding domains fused to the C-termini of the heavy chains and the light chains of HC2:LC1; or (v) HC2-AFL:LC1-AFL, a hexavalent antibody comprising aflibercept-derived VEGF-binding domains fused to the C-termini of the heavy chains and the light chains of HC2:LC1. After treatment, the cells were rinsed with ice cold PBS containing 1 mM NaOV and lysed in Complete Triton X Lysis Buffer (20 mM Tris-HCl, 137 mM NaCl, 10% Glycerol, 1% Triton X-100, 2 mM EDTA, 1 mM NaOV, 1 mM NaF, 1 mM PMSF, 1 μg/mL leupeptin, 1 μg/mL pepstatin).

The lysates were immunoprecipitated with anti-Tie2 and anti-VEGFR2 antibodies. 1-10 μg of VEGFR2 antibody (MAB3573, #89109), TIE-2 antibody (Ab33), and 25 μL of Protein A/G agarose beads were added to 1 mL of HUVEC lysate, and the tubes were placed on a rotating platform for 1-3 days at 4° C. The IP reaction tubes were rinsed with 1 mL complete Triton-X lysis buffer and resuspended in 2× loading dye containing DTT. The tubes were incubated at 95° C. for five minutes, spun down, and 25 μL loaded per well into a Tris Glycine gel. The samples were resolved on a gel, transferred to a PVDF membrane, and subjected to serial western blot to detect phosphotyrosine (phospho-Tie2 and phospho-VEGFR2), followed by re-probing to blot for total Tie2, and total VEGFR2. The gel was run at 125V for 75 minutes, before transfer to a PVDF membrane. The membranes were blocked in 5% BSA/0.05% Tween Tris Wash Buffer for 1 hour at room temperature (RT) on a rotating platform. Primary antibodies (PY99; VEGFR2-A3; TIE-2 Ab33) were added for 1 hour at a 1:1000 dilution in wash buffer. Secondary antibody (anti-mouse hrp) was added for 1 hour at a 1:1000 dilution in wash buffer. The membranes were rinsed three times with 0.05-0.1% Tween 20+Tris Buffered Saline (TBS) between steps. An ECL detection system was used to visualize bands. Re-probe was performed on lots treated with 200 mM Glycine for 24-48 h.

As shown in FIG. 19, all of the tested bispecific antibodies increased basal Tie2 activation in HUVECS, while basal VEGFR2 phosphorylation was not affected. The top panel provides a western blot showing Tie2 activation and VEGFR2 activation as shown through detection of phospho-Tie2 and phospho-VEGFR2, respectively (top half), and total Tie2 and VEGFR2 (bottom half). The bottom panel provides the densitometric ratios of phosphorylated Tie2 to total Tie2.

The assay was repeated with the following antibodies of the disclosure, which also enhanced Tie2 activation in the absence of exogenous Ang1: (i) HC2-RAN:LC1, (ii) HC2-ABI:LC1, (iii) HC2:LC1-AFL, (iv) HC2:LC1-BRO, (v) HC2:LC1-ABI, and (vi) HC2-ABI:LC1-ABI.

Cell maintenance was performed using complete medium (EGM or EGM-2) and sub-cultured using Trypsin/EDTA into 100 mm dishes. After 3 days, the 100 mm dishes were rinsed, and mock-pre-treated or pre-treated in basal medium (EBM, EBM-2, OptiMEM I) for 30 minutes at 37° C./5% CO₂ with one of the following antibodies at 5 or 50 nM as indicated in FIG. 20: (i) HC2:LC1, a humanized monoclonal antibody specific for HPTP-β; (ii) HC2-BRO:LC1, a tetravalent bispecific antibody comprising brolucizumab-derived VEGF-binding domains fused to the C-termini of the heavy chains of HC2:LC1; (iii) HC2-AFL:LC1, a tetravalent bispecific antibody comprising aflibercept-derived VEGF-binding domains fused to the C-termini of the heavy chains of HC2:LC1; (iv) HC2-BRO:LC1-BRO, a hexavalent antibody comprising brolucizumab-derived VEGF-binding domains fused to the C-termini of the heavy chains and the light chains of HC2:LC1; or (v) HC2-AFL:LC1-AFL, a hexavalent antibody comprising aflibercept-derived VEGF-binding domains fused to the C-termini of the heavy chains and the light chains of HC2:LC1. After pre-treatment, cells were treated with VEGF (5 ng/mL) and Ang1 (50 ng/mL) for 6 minutes at 37° C./5% CO₂ in basal medium (Phosphate buffered saline, PBS+0.2% Bovine Serum Albumin, or OptiMEM I). After treatment, the cells were rinsed with ice cold PBS containing 1 mM NaOV and lysed in Complete Triton X Lysis Buffer (20 mM Tris-HCl, 137 mM NaCl, 10% Glycerol, 1% Triton X-100, 2 mM EDTA, 1 mM NaOV, 1 mM NaF, 1 mM PMSF, 1 μg/mL leupeptin, 1 μg/mL pepstatin).

The lysates were immunoprecipitated with anti-Tie2 and anti-VEGFR2 antibodies. 1-10 μg of VEGFR2 antibody (MAB3573, #89109), TIE-2 antibody (Ab33), and 25 μL of Protein A/G agarose beads were added to 1 mL of HUVEC lysate, and the tubes were placed on a rotating platform for 1-3 days at 4° C.

An ECL detection system was used to visualize bands. Re-probe was performed on lots treated with 200 mM Glycine for 24-48 h.

Treatment with VEGF and Ang1 resulted in increased phosphorylation of VEGFR2 and Tie2 (FIG. 20). Treatment with the HC2:LC1 antibody, specific for HPTP-β, enhanced Ang1-mediated Tie2 activation in cells treated with Ang1 and VEGF. Treatment with the bispecific antibodies enhanced Ang1-mediated Tie2 activation and blocked VEGF-mediated VEGFR2 activation in cells treated with Ang1 and VEGF. The top panel provides a western blot showing Tie2 activation and VEGFR2 activation as shown through detection of phospho-Tie2 and phospho-VEGFR2, respectively (top half), and total Tie2 and VEGFR2 (bottom half). The lower panel provides the densitometric ratios of phosphorylated Tie2 to total Tie2 and phosphorylated VEGFR2 to total VEGFR2.

Example 18: Multi-Specific Antibodies Bind HPTP-β and VEGF at High Affinity (Biacore Surface Plasmon Resonance Assays)

Biacore surface plasmon resonance assays were performed to determine the equilibrium dissociation constant (K_(D)) of antibodies of the disclosure for VEGF and HPTP-β (VE-PTP). Binding experiments were performed on Biacore 3000/Biacore T-200 instruments at 25° C.

The assay buffer contained 10 mM HEPES buffer (pH 7.4), 150 mM NaCl, 3 mM EDTA, and 0.05% P20 (polyoxyethylenesorbitan). The regeneration buffer contained 10 mM Glycine buffer (pH 1.75). The conjugation buffer contained 10 mM sodium acetate buffer (pH 5). A flow rate of 5 μL/minute was used for capturing ligand. A flow rate of 30 μL/minute was used for kinetic analysis.

For analysis of binding of antibodies to HPTP-β, poly-histidine tagged HPTP-β extracellular domain (ECD) 1/2 was immobilized on a chip surface via anti-His antibodies. Goat anti-His antibody was first immobilized on the surface of the chip by direct immobilization using EDC/NHS (N-ethyl-N′-(3-dimethyl aminopropyl carbodiimide)/N-hydroxy succinamide) coupling chemistry on flow cell 2 of the CM5 (Carboxymethylated dextran coated) chip. Unoccupied sites were blocked with 1M ethanolamine. The His-tagged ligand HPTP-β 1/2 ECD was captured at a response unit (RU) of 50. The analyte (antibody) was flowed over the chip at a single analyte concentration at a time. The binding of analyte to the ligand was monitored in real time to obtain on (k_(a)) and off (k_(d)) rates. The equilibrium constant (K_(D)) was calculated from the observed k_(a) and k_(d).

For analysis of binding of the antibodies to VEGF, the antibodies were immobilized on the surface of the chip by direct immobilization using EDC/Ni s coupling chemistry on flow cell 2 of the CM5 chip. Unoccupied sites were blocked with 1M ethanolamine. The analyte (VEGF) was flowed over the chip at a single analyte concentration at a time. The binding of analyte to the ligand was monitored in real time to obtain on (k_(a)) and off (k_(d)) rates. The equilibrium constant (K_(D)) was calculated from the observed k_(a) and k_(d).

Scouting analysis was performed using 10 nM of analyte to determine approximate K_(D). Chi square analysis was carried out between the actual sensorgram and the sensorgram generated from the BIAnalysis software to confirm the accuracy of the analysis; values of 1-2 were considered accurate and below 1 highly accurate.
